摘要：

Theoretical and experimental analyses are presented of the effects of phase errors in the components of an optical correlator.A position dependent treatment of the wavefront phase error of the optical system is needed to determine how these errors propagate through the system and their effect on the output correlation.The empirically determined expression R = 1 − 0.5ϕ2 is found to describe the loss in intensity of the correlation peak in terms of the phase error ϕ in the first transform lens.© 1979 Optical Society of America.
